The little larvae finds a nice spot on the sea floor and becomes a polyp after 3 months. A tree like growth will form and a little Jellybee will be seen. Yes! They are born upside down! After the Ephrya stage, the Jellybee will become a mature adult called a Medusa just like real jellyfish. Did you know, Jellybee's have gills under their fur, it cant be seen on adults but if you look close on the Ephyra stage, its right on the neck! They are water and land creatures, though water is 98% of their preference due to easy dehydration and weak immune systems.
